Al Hall (Sterling Heights, Michigan, United States)
Very expensive test tube.

Ordered what you call a quarts sleeve because brand new one broke while being installed. The new one at $27.00 was pre cracked on the end. Waiting to come home to a water leak. Part is way too thin!

Perfect!

It was delivered earlier than expected and it was well packed.
